Zusammenfassung:	To provide a heat expansion material fixture capable of securely preventing spread of fire, a compartment penetration tool provided with the heat expansion material fixture, and a fireproof compartment penetration tool provided with the heat expansion material fixture or the compartment penetration tool.SOLUTION: A heat expansion material fixture 3 in order to install hear expansion material 5 expanded by receiving heart in a through hole configured to pass through a compartment body dividing the inside of a building or the inside from the outside has fire resistance and comprises a cylindrical body formed into a cylindrical shape so as to be inserted in the through hole. The cylindrical body is configured such that the heat expansion material becomes an outer wall to mainly expand radially inward when the heat expansion material installed inside of the cylindrical body expands be receiving the heat, and is provided with an extension allowing part allowing a part of the hear expansion material to extend to an outer area in a radially outward direction of the cylindrical body.SELECTED DRAWING: Figure 2 【課題】より確実に延焼することを抑制できる熱膨張材取付具、該熱膨張材取付具を備える区画貫通具、及び、前記熱膨張材取付具又は前記区画貫通具を備える耐火区画貫通具を提供する。【解決手段】建築物の内部又は内部と外部を区画する区画体を貫通するよう形成された貫通孔に、熱を受けて膨張する熱膨張材５を設置するための熱膨張材取付具３であって、耐火性を有し、貫通孔に挿入可能となるように筒状に形成された筒状体を有し、筒状体は、筒内部に設けられる熱膨張材が熱を受けて膨張する際に熱膨張材が主として径内側へ膨張するための外壁となるよう構成され、熱膨張材の一部が筒状体の径外方の外部領域に延出することを許容する延出許容部を備える。【選択図】図２
